invention is a directed broadly to a construction of cellulose sanitary liners-for basins. The "sanitary liner which I have-illustrated has been -developed particularly in connection with washbasing-but; I desire that-it be understood that the sanitary insert of my invention maybe employed forbasins used to hold liquids of any description for medical treatments in doctors "and'dentists 'ofiices, in chemical research laboratories, andin other instances where quantities--=ofliquid must bemain-tained in a vessel. 'Myinvention is intended primarily for use inthe automatic insert basin set' forth more fully --in my parent application ---Seria1 April--18, '1935, supra, which-provides meansfor successively supplying to a basin a sanitary liner -='of -'cellulose-= material which is I normally folded -and* arranged in manifold-relation Withsimilar ='-liners in a magazine carrier. -ofthe lineris such that the flat Walls'thereof =-may be readily unfolded to form a liquid re- =taining receptacle in a basin having perforate walls. The construction of'the basin is such that it will itself not normally retain fluid. *How- 40 "ever;-wh'en a-sanitary liner is inserted in the basin and opened to conform with theinternal shape of the basin, fluidcan be retained in the "liner forming "the receptacle. "Thepresent application shows'means for ejecting-the liner after use. For this purpose adrain' housing-isprovided 'beneath the basin and connected with the 'dr'ain from the basin. Anyejecting mechanism -is employ'ed' to effect the discharge of the used 'liner's'to-aposition within-the drain housing. At

periodic intervals, the used liners are removed from the drain housing.

Where it is desired to employ the sanitary liners for wash basins in public places, such as hotels, comfort stations, railroad trains, etc., I

The construction :35

purposes of explaining my invention may be, formed from a cellulose product which is substantially liquid-proof to insure the retaining of g the liquid within the basin. I have illustrated the cellulose insert in Figs. 1-6 from which itwill be seen that there are two flat wall portions 3: and 3b which may be folded in fiat surface.

contact as shown in Fig. 5. The side wallsof the insert may be folded as shown at 3c and 3d to insure a fiat structure capable of manifolded assembly while readily permitting the unfolding of the end portions 30 and 311 to the position illustrated in Figs. 2, 3 and 6. Various forms of cellulose materials may be used and a selection of the exact material is not important. I have found paper which is waxed or otherwise treated to be practical as a manifolded insert.

I make provision for folding the side wal1s73w and 3b through the agency of the web-like end portions 30 and 3d, which when folded inwardly allow the sanitary insert to be collapsed to a substantially rectangular package. This facilitates the manifolding of the sanitary inserts in the delivery mechanism which I have shown .herein' for the purpose of explaining the nature of the problem which must be made in the construction of the sanitary insert of my invention.

I'he sanitary liners 3 are stored in manifolded relation as indicated at l3 in a magazine carrier 54 located directly beneath the front of the top section 50 of the fixture constituting the basin as illustrated. The magazine carrier 54 supports the liners in manifolded relation as indicated at l3 in a position in which the liners 3 may be successively fed to the basin by a vertically upward movement. Fig. 8 illustrates one of the liners 3 being fed in a vertical direction intermediate the end plate 55 and the edge 56 of the top section 50 and through the slot 51 formed in the upper portion of the magazine carrier 54. The sanitary liners 3 are continuously urged in the direction of plate 55 by means of springs 2| acting between the inside face of the magazine carrier 54 and the follower plate 59. The feed mechanism for the sanitary liners '3 includes the liner pickup fingers l4 carried by a laterally extending bar member H. The pickup bar member I1 is mounted to move with a slight amount of lost motion in the ends of the pickup bar arms l6 so that the liner pickup fingers may follow each sanitary liner successively for insuring the delivery. of each sanitary liner ina vertical path. The pickup bar arms l6 are carried by a pivoted bar H! which is journaled in bracket members 60 mounted on the rear surface of the magazine carrier 54. An operating lever 20 is connected with the pivoted bar i9 and to the pickup arms I6 and has an end grip 6i thereon which may project beyond the front of the top section 50 in a convenient position and manually gripped for angularly shifting the liner pickup fingers l4 and effecting the ejection of each successive sanitary liner 3. The pickup bar I! is adapted to slide vertically within limits defined by the pickup bar guide slot 26 formed in the vertically extending portions of the end closures of the basin indicated at 49 in the cross sectional views.

The lever 20 is normally maintained in an extreme upper position illustrated in Figs. 7, 9 and 10 by means of a suitable coil spring. With each successive actuation of lever 20 the coil spring returns lever 20 to its extreme uppermost position ready for its successive operation.

"In order-to replenish the supply of sanitary liners in the magazine carrier I provide a refill do or;l,5 hingedly mounted at 3| to allow sanitary linersin manifold relation to be inserted into the compartment as the liners are used from time to time. A suitable lock 62 is provided for pre- ..venting unauthorized access to the magazine carrier.

Inorder-to. open the refill door l5 the lock 62 is unlocked, the sanitary liners in manifold relation inserted in the compartment and the successive feeding of the sanitary liners thus con- -tinued.-. The sanitary liner3= is substantially troughlike in contour and has the major longitudinally extending axis thereof exceeding in dimension the lateral axis normal thereto. The V-shaped construction of the sanitary insert which conforms withthesides ofthe recessed portion of the basin in which it is inserted is an important .factor in determining the strength of the sanitary insert. It is important that the insert have considerable strength in order that the insert -may be practically employed in the delivery mechanism which I have explained. When the sanitary insert is unfolded, the walls conform with the sides of the basin for which it provides a sanitary liner.

--, :While I' have described a preferred embodimentof my'invention I desire that it be understood that modifications may be made, and I intend .no limitations upon my invention other than may be imposed by the scope of the appended claim. a What I claim as newand desire to secure by Letters Patent of' the United'States is as follows: 1' A sanitary insert for basins comprising an ele ment of sheet-like material foldable in a substantially rectangular package adapted to be ejected froma magazine. carrier, said element comprising a pair of side wall portions and a pair of triangular shaped end wall portions of web-like construction interconnecting opposite ends of the side wall portions, said web-like end portions being normally folded inwardly to per- .mit saidliner to be maintained in a flat package and being unfoldable to allow said side walls to be moved to a position angularly displaced with respect to each other for-forming a substantially fiuidtight container, said container being collapsiblealong substantially the center of the side walls thereof for allowing ejection of the container after use thereof.
